Boss’s Day, celebrated on October 16th, has traditionally been a day for employees to thank their bosses for being kind and fair throughout the year.

Patricia Bays Haroski registered “National Boss’ Day” with the U.S. Chamber of Commerce in 1958. She was working as a secretary for State Farm Insurance Company in Deerfield, Illinois at the time and chose October 8 because she forgot that the birthday of her boss, who was her father, was actually on the 16th. Four years later, in 1962, Illinois Governor Otto Kerner backed Haroski’s registration and officially proclaimed the day.

In recent years, National Boss’ Day has become an international celebration and now is observed in countries such as Australia, India, South Africa, Ireland, the UK, and Egypt.
